Hazard Cause Conse-
quences
Remedial actions, safety
information
Loosening of screw connec-
tions, nullication of the
effectiveness of the clutch/
brake: Breakage of screws
due to excessively high pres-
sure, use of screws with too
low property classes, too few
screws, loosened screws
Stability/structural
safety
Running over,
sliding away,
crushing
Observe data in the OI/drawing, screw tight-
ening torque, check number and property
class, secure screws against loosening,
observe and monitor max. permissible
pressure
Thermal hazards:
Dynamic clutch/braking proc-
esses, high speeds, oil level
in the brake too high (wet
running)
Objects or mate-
rials with high or
low temperature
Burning Operator instructions, clearance grill or
temperature sensor, observe oil ll quantity,
monitor speeds
Noise hazards:
Contact with parts under the
inuence of speed, incorrect
installation position (radial/
axial) and locking of inner
drive/shaft to outer drive,
operating pressure/air pres-
sure too low or missing, incor-
rectly aligned parts
Moving parts Discomfort, stress Check the fastening of the clutch/brake and
the inner drive, check installation position in
accordance with drawing, check for freedom
of movement of the clutch/brake, observe
and monitor minimum necessary operating
pressure/air pressure and monitor piston
end position if necessary
Dynamic clutch/brake proc-
esses
Friction surfaces Discomfort, stress None
Radial misalignment between
inner drive and outer drive
Out-of-balance
rotating parts
Discomfort, stress Check the fastening of the clutch/brake and
the inner drive, check installation position in
accordance with drawing, check for freedom
of movement of the clutch/brake
High speed, large gap
between discs
Worn parts Discomfort, stress Check clutch/brake pads regularly for abra-
sion, replace discs if necessary, observe or
monitor speed limits
Oscillation hazards:
High rotational speeds Misalignment of
moving parts
Discomfort, stress Check the fastening of the clutch/brake and
the inner drive, check installation position in
accordance with drawing, check for freedom
of movement of the clutch/brake, comply
with speed limit and monitor if necessary
Worn parts Discomfort, stress Replace worn parts, comply with speed limit
and monitor if necessary
Material/substance hazards:
Leaks: Operation with leaking
clutch/brake (wet running),
with assembly/disassembly of
the pressurised oil connec-
tions
Aerosol, uid,
vapour
Respiratory prob-
lems, allergisation
Clutch/brake leaking externally, apply liquid
sealant to all clutch/brake joints and the
connection parts, check leak-tightness prior
to commissioning or at appropriate intervals
during operation
Operation with non-sealed
clutch/brake (dry running)
Dust Allergisation None
Hazards in connection with the operational environment of the machine
Under static and dynamic
loading of the clutch/brake:
Inuence on the function
and the torque through the
effects of corrosion and the
aging processes of organic
substances
Impurities, dust,
moisture
Running over,
crushing
At appropriate intervals: Check load-bearing
parts of the clutch/brake for corrosion, oil
change, check function, if necessary house
and protect clutch/brake unit from corrosion,
replace corroded or damaged parts
